This on-demand natural ventilation system is suitable for new construction and renovations . The Duco Focus System measures the CO 2 rate and humidity using a patented adjustment valve system located under the cover of the DucoBox Focus ventilation box. The extraction takes place in a zonal way (7 zones maximum) , but can be extended to 11 spaces thanks to the unique splitter.
The DucoBox Focus is an extractor fan that ensures zonal extraction in Duco Natural Demand Ventilation (NDV) Systems. The DucoBox Focus is both the engine of the system and the "master" unit to which the control components can be connected.
This quiet, compact, durable and extremely energy efficient exhaust fan exhausts humid and/or stale air when and where needed, and in the right amount. The integrated dampers (to be ordered separately) also ensure that the air is only extracted where it is needed , guaranteeing even quieter and more energy-efficient operation. Simple structure and efficient DC motor ensure long service life.
This version allows, thanks to the addition of an intelligent control panel, to integrate a patented system of adjustment flaps in the extraction box itself. The DucoBox Focus is supplied as standard with seven connections (ø 125 mm), all of which can optionally be equipped with dampers. Each damper can be optionally equipped with a CO 2 sensor or a hygrometric probe allowing measurement directly IN the air flow itself. It is also possible to opt for a damper without probe. The discharge rate of each damper is factory set according to the requirements in force, but the installer can always manually adjust this setting if necessary.
The DucoBox Focus allows you to ventilate up to 11 rooms thanks to adjusting valve splitter . In this way, the possibilities of application are greater and the ventilation only intervenes at the places and at the necessary times!
In fact, the Adjustment valves splitter is capable of duplicating the DucoBox Focus taps. Thus a zone ventilation system with up to a maximum of 11 connections (of which a maximum of 7 connections for CO2 control valves) can be created. Using a supplied connector, the damper wiring can easily be plugged into the DucoBox Focus. And this, as always in Duco systems, invisibly behind the cover!
